I'll shut up about ereaders and ebooks and anything else that involves taking a regular word and then sticking an 'e' in front of it, but I just wanted to share one last thing that makes me happy about my Sony PRS-600:
One thing they got completely right is that when I switch it on it takes maybe three seconds to go from switched off to looking at the last page I read.
That's faster to boot up than my MP3 player. It's faster than my TV or my mobile phone. It's so much faster than my PC that I could switch them on at the same time and read a few pages while I wait for the computer to get its act together.
I'm not sure I could find my place any quicker with an old fashioned, dead-tree book.
